DETAILED DESCRIPTION OF THE INVENTION

As can be seen in the figures, the device according to the invention comprises a supporting structure preferably constructed of steel profiles forming vertical supports 4, longitudinal members 8, transverse members 10 and any reinforcement, the supporting structure being sized to withstand the maximum foreseeable load. Said profiles are suitably joined together by screwing or welding.

For the sake of simplicity, one particular arrangement of this structure will be described in detail, comprising two identical towers generally designated 2, 2 'whose faces are facing each other and spaced apart at a distance suitable to allow the platform 12 to move the motor vehicle 14 between them. The two towers 2, 2 'have the shape of a prism with different sections of structure arranged in several superimposed rows of cells 16, each adapted to park one vehicle 14 side by side with vehicles parked in the other cells.

-2GB 282505 B6

In the detailed embodiment, the input cell 16 'is in the outer cell of the lower row of one tower 2 and the output cell 16 is located in the outer cell of the other tower 2'.

Two base cross members 10 of each cell 16. 16 '. 16 support four longitudinal guide members 6, 6 ', namely two outer longitudinal guide members 6 and two inner longitudinal guide members 6' that are parallel to the longitudinal members 8 of the support structure. The purpose of the longitudinal guides 6, 6 'is to support and guide the pallet 18 supporting the motor vehicle 14. The pallet 18 has two parking tracks 20 and a connecting plate 22 which connects these parking tracks 20 to each other.

Each parking track 20 is formed of a substantially C-shaped steel sheet opened upwardly and is supported by a plurality of small transverse members 24 welded to the lower surface thereof and provided with bearings 26 at their ends for traveling along the lower flange of the respective longitudinal guide members 6, 6. 'tower 2, 2'. The ends of the transverse members 24 are also provided with bearings 26 'with a vertical axis, which are supported on the vertical web of the longitudinal guide members 6, 6' for laterally guiding the pallet 18.

Each parking lane 20 comprises a pair of double-sided wedges 28 spaced apart so that their distance is slightly greater than the maximum wheelbase of vehicle designs 14 to ensure that the wheels of all vehicles 14 rest on the parking lanes 20 when parked. between the wedges 28, which in this way constitute a stop for the vehicle 14 even if it is not braked.

The two wedges 28 are fixed to the floor of each respective parking track 20, but in one embodiment not shown in the drawings, they can be adjustable in the longitudinal direction of the parking track 20 so that they can adapt to the wheelbase of vehicles 14 with special dimensions.

The wedges 28 may be mechanically adjustable by known systems preferably controlled by a sensing device which senses the contour of the vehicle 14 and accordingly adjusts the position of the wedges 28 so that the respective vehicle 14 does not extend beyond the edge of the pallet 18.

In the middle position below the plate 22 connecting the two parking tracks 20 to each other, two parallel projections 30 are welded to the plate 22, which face downwards. The two projections 30 have parallel vertical surfaces, each having an aperture 32 coaxial with the aperture 32 in the second projection 30. Their inner surface, i.e. the surface facing the second projection 30, has bevelled vertical edges.

The two inner longitudinal guide members 6 'of each parking cell 16 are connected to each other in their midst by a supporting cross member 34, in the middle part of which the holding member 38 is fastened by the support 36 for holding the respective pallet 1.8. This retaining member 38 consists of a cylinder positioned parallel to the support cross member 34 and has two pins 40 extending from opposite ends of the cylinder by the action of a helical spring 42 disposed therebetween. Each of the two pins 40 is provided within the cylinder chamber of the retaining member 38 with a toothed protrusion 44 engaging a common gear 46 that provides simultaneous counter-directional movement of the two pins 40 for the purpose described below. The dimensions of the retaining piece 38 are such that when the two pins 40 are fully drawn into the cylinder, the whole unit rests between the two projections 30, while, when both pins 40 protrude from the cylinder, they are inserted into the respective two holes 32 in the cylinder. the protrusions 30 when the pallet 18 is positioned centrally on the longitudinal guides 6, 6 '.

A centering piece consisting of a centering plate 48 provided with a funnel-shaped opening 50 is welded to the lower flange of the two inner longitudinal guide pieces 6 'at the end facing the opposite tower.

-3GB 282505 B6

As mentioned, another essential part of the invention is a platform 12 for handling vehicles 14. The platform 12 is supported by a vertical structure 52, which is located between the two towers 2, 2 'and can move within their space.

More specifically, this vertical structure 52 comprises two vertical stands 54 provided at their upper ends with sliding carriages 55 that slide along the longitudinal upper guide rail 56 supported by beams 57 that connect the two towers 2, 2 'to each other and support an optional roof. Bottom on the floor of the passage delimited by the two towers 2, 2 'is a lower guide rail 59 with which a rack 60 is connected, into which a gear 61 mounted on the shaft of an electric motor 62 engages to move the vertical structure 52 along the rails 56, 59.

On both vertical stands 54 as high as the two towers 2, 2 ', the beam slides to its ends to which four longitudinal guide pieces 64, 64' are attached, having the same shape, dimensions and arrangement as the four longitudinal guide pieces 6, 6 ' each parking cell 16.

Also attached to each rack 54 of the vertical structure 52 is a vertical hydraulic piston unit 66 whose rod 68 extends upwardly and is provided at its end with a sprocket 70 through which the chain 72 extends. This chain 72 is secured to its respective rack 54 at one end. the other end to the beam 63, which is slidably movable along the vertical stands 54, so that each synchronized extension of the two vertical piston units 66 by a certain distance causes a vertical movement of the beam 63 by twice that distance.

The double-acting longitudinal piston units 74, 74 'are connected to two inner longitudinal guide parts 64' supported by the beam 63. Each longitudinal piston unit 74, 74 'comprises a cylinder 76, 76' whose length is substantially the same as the length of the inner longitudinal guide parts 64 '. a bar 78, 78 'slidably mounted in the cylinder 76. 76' and an outer shell 80, 80 'which extends longitudinally completely around said cylinder 76, 76' and almost completely surrounds it around its periphery except for the narrow longitudinal slot for the passage of the brackets 81 a cylinder 76, 76 'to the inner longitudinal guide member 64' and two connections for the inlet and outlet of the working fluid. The end of the rod 78, 78 'extending from the respective cylinder 76, 76' is attached to the end piece 82 connected to the outer shell 80, 80 ', the two hydraulic piston units 74, 74' being positioned in opposite directions so that the respective rods 78, 78 'happens in opposite directions.

The carriages 84 provided with bearings for their movement and guidance along the upper flange of the respective inner longitudinal guide portion 64 are fixed at several longitudinally spaced apart points on the outer casing 80, 80 'of each hydraulic piston unit 74, 74'. the purpose of which is to support the rod 78, 78 '. when it is extended from the cylinder 76, 76 'and maintain its axis substantially in a straight line regardless of the length of its extension. A small hydraulic piston unit 86, 86 'is mounted across the same outer shell 80, 80', i.e. its axis is perpendicular to the axis of the longitudinal hydraulic piston units 74, 74 '. The diameter of the rods 88, 88 'of these transverse piston units 86, 86' is such that their rod 88, 88 'can engage with the corresponding projection 30 of the pallet 18 from the outside in the extended state.

At both ends, each inner longitudinal guide portion 64 'is provided with an additional hydraulic piston unit 90, the rod 92 of which is of a diameter such that it can engage into the aperture 50 in the centering plate 48 to achieve accurate alignment of the longitudinal guide members 64. 64 'with the longitudinal portions 6, 6' of the parking cell 16 to which the platform 12 is to be positioned.

The device according to the invention also comprises a plurality of actuators, limit switches and automatic means of various types for the correct execution of the duty cycle. All of these components, which are preferably controlled by a microprocessor, are of the conventional type and do not require further explanation.

-4GB 282505 B6

To facilitate understanding of the operation of the device according to the invention, a situation considered to be an initial situation in which some parking cells 16 are filled with a motor vehicle 14 located on the respective pallet 18 and other parking cells 16 are empty, i. the pallets 18 without vehicle 14. The total number of stalls is N-2, where N is the number of cells 16, and each pallet 18, with or without the vehicle 14, is supported by two parking tracks 20 on transverse sections 24 resting on the longitudinal sections. 6, 6 'and is securely connected to the respective parking cell 16 by engagement between the two pins 40 of the retaining member 38 and the two projections 30 of the pallet 18.

The control computer has information on both the extent of occupation of the different cells 16, i. whether each individual cell is free or occupied, as well as the position of the platform 12 that manipulates the vehicles 14 and which may be, for example, in front of the input cell 16 ', i.e. between the input cell 16' and the output cell 16 ''. For clarity, it should be noted that the empty pallet 18 is already placed in the input cell 16 'and that one parking cell 16, which in Fig. 1 contains a vehicle 14 shown in broken lines, and the output cell 16 are both without the pallet 18 .

If, under these conditions, the vehicle 14 arrives in front of the barrier 93 controlling access to the input cell 16, the conventional automat will eject a magnetic card with a record of the arrival and customer-specific data.

Removing the card from the dispenser activates the bolt 93 in a conventional manner to release the vehicle 14 and allow it to be lifted, possibly with two ramps, into the input cell 16 '. At this point, the vehicle 14 has four wheels on two parking lanes 20 between the four wedges 28, which, as mentioned, act as stops for the vehicle if the driver forgets to apply the parking brake.

After the driver leaves the vehicle 14, he inserts a magnetic card into a reader device that reads the recorded data and transfers it to the control computer for use together with the data already contained in the computer, in particular concerning the position of the target parking cell 16.

The transfer phase begins with a command to eject the bars 92 of all four centering piston units 90 by engaging holes 50 in centering plates 48 firmly connected to the longitudinal guide portions 6 'of the input cell 16' and the output cell 16 to achieve accurate alignment between the four longitudinal portions 64 , 64 'of platform 12 and four longitudinal portions 6, 6' of said cells 16 ', 16.

Upon completion of this operation, oil is supplied to the double-acting longitudinal piston unit 74 from which the rod 78 extends and the respective housing 80 is displaced in the direction of the input cell 16 '.

The end position of the path of the double-acting longitudinal piston unit 74 corresponds to the position in which the respective transverse piston unit 86 is aligned with the retaining member 38 of the pallet 18 of the input cell 16, i.e. in a position in which the transverse piston unit 86 is opposite one of the two protrusions 30 At this point, another automatic command causes the rod 88 of the transverse piston unit 86 to extend and insert into the bore 32 of the projection 30, and push the peg 40 into the retainer 38 by means of a toothed connection between the two pins 40 of the retainer 38 upon return. One of these pins 40 in its cylindrical housing also returns the corresponding second pin 40, resulting in subsequent release of the two projections 30. Thus, by operation of the tower piston unit 86 holding the pallet 18 is transferred from the holding piece 38 permanently installed in the input cell 1. 6 'to the longitudinal piston unit 74 fixedly mounted on the platform 12. Following the reverse command, the piston unit 74 retracts the bar 78 into the cylinder 76 to move the pallet 18 with the vehicle 14 standing thereon onto the platform 12. This operation is effected by rolling the bearings 26, 26'. along the longitudinal portions 6, 6 'of the input cell 16' and then along the longitudinal portions 64, 64 'of the movable platform 12. It should be noted that once the pallet 18 begins to move towards the movable platform 12 and its projections 30 move from the position against the holding 38, the two pins 40 return to their outwardly protruding position by the resilient spring 42 located in the retaining member 38.

-5 II

When the pallet 18 reaches a position in which it is supported only by the longitudinal guides 64, 64 '. the centering piston units 90 are released to completely disconnect the platform 12 from both the cells 16 ', 16, thereby allowing suitable commands for the electric motor 62 to move the vertical structure 52 and for the vertical piston units 66 to lift the platform 12 along the vertical structure 52 to move said the platform 12 to a position against the parking cell 16, which does not include a pallet 18 in accordance with the data available to the control computer.

In the drawings, it is assumed that this parking cell 16 is located in the tower 2 ', opposite the tower 2 containing the entrance cell 16'. When the movable platform 12 has reached the target parking cell 16 and the electric motor 62 and the vertical piston units 66 are at rest, the centering piston units 90 are commanded to secure the platform 12 to the target cell 16 and the opposite cell of the second tower 2 to achieve accurate alignment between parts 64, 64 'and 6, 6'.

Once the rods 92 of the piston units 90 have taken up the apertures 50 in both centering plates 48, another longitudinal piston unit 74 'is commanded to move the pallet 18 with the vehicle 14 to the target parking cell 16.

During the final phase of this displacement, the projections 30 of the pallet 18 interfere with the pins 40 resiliently protruding from the retaining member 38 of the target parking cell and engage them in the cylindrical housing. Upon completion of this travel, the two pins 40 remain in the retracted state despite the holes 32 formed in the projections 30 facing them because one of these holes is occupied by the rod 88 'of the transverse piston unit 86'. When the bar 88 'is forced to retract, the two pins 40 of the retaining member 38, which move simultaneously, can spring out under the action of the spring and securely lock the pallet 18 in the target parking cell 16.

The rod 78 'of the longitudinal piston unit 74' is then retracted, followed by the rod 92 of the centering piston units 90 to release the movable platform 12 from the cell that has just been filled.

At this point, various operations may be performed according to a computer control program, all of which are within the scope of the invention. For example, the movable platform 12 may pull an empty pallet 18 from another parking cell 16 and move it to the input cell 16 'to repeat the cycle described when another vehicle arrives. Alternatively, the movable platform 12 may remain in the previous position and await a command that may be either placing another vehicle 14 in another free parking cell 16 or pulling the vehicle 14 out of the occupied parking cell 16 in the event of a parking time. In this case, after verifying that the output cell 16 does not contain the pallet 18, the entire described control cycle is repeated in reverse order. Obviously, to correctly position the vehicle 14 in the cell 16, 16 '. 16 or pulling the vehicle out of cell 16, 16 ', 16 must not be in the target cell 16, 16'. 16, and therefore the control program includes this verification prior to performing the transfer of the pallet 18 supporting the vehicle 14.

As mentioned above, a description of a certain embodiment of the device according to the invention has been described in which the movable platform 12 is provided with two double-acting longitudinal piston units 74, 74 ', each of these piston units 74, 74' being designed to move a pallet 18 of platform 12 into one of the two towers 2, 2 'and vice versa. If the device according to the invention comprises only one tower 2, it is clear that one double-acting longitudinal piston unit 74 is sufficient.

Giant. Figures 9 to 14 schematically show another embodiment of the invention. Specifically, FIGS. 9 and 10 illustrate a device having an arrangement similar to the previous case, but with an input cell 16 'that is identical to the output cell 16. wherein the vehicles 14 are arranged in series in different parking cells 16.

-6GB 282505 B6

Giant. 11 and 12 show a device whose arrangement comprises two towers 2, 2 'as in the case of FIG. 1, but these towers are partly underground and partly above ground. The input cell 16 'and the output cell 16 are located in a row at ground level in the middle of the object but are not aligned against each other.

Finally, FIGS. 13 and 14 show an arrangement comprising two towers 2, 2 'completely below ground level, wherein the input cell 16' is identical to the output cell 16.

In view of the different types shown, the invention may be considered to include all combinations obtained by combining different characteristics.
